Lack of sleep may be linked to risk factor for Alzheimer’s disease – Study

This is kind of a yin/yang thing with exercise vs rest. Just as I write about the myriad benefits of exercise regularly here, it seems there are almost as many ways that not getting enough sleep damages us. If you would like to learn more, check out my Page – How important is a good night’s sleep?

Losing just one night of sleep led to an immediate increase in beta-amyloid, a protein in the brain associated with Alzheimer’s disease, according to a small, new study by researchers at the National Institutes of Health (NIH). In Alzheimer’s disease, beta-amyloid proteins clump together to form amyloid plaques, a hallmark of the disease.

While acute sleep deprivation is known to elevate brain beta-amyloid levels in mice, less is known about the impact of sleep deprivation on beta-amyloid accumulation in the human brain. The study is among the first to demonstrate that sleep may play an important role in human beta-amyloid clearance.

“This research provides new insight about the potentially harmful effects of a lack of sleep on the brain and has implications for better characterizing the pathology of Alzheimer’s disease,” said George F. Koob, Ph.D., director of the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health, which funded the study.

Beta-amyloid is a metabolic waste product present in the fluid between brain cells. In Alzheimer’s disease, beta-amyloid clumps together to form amyloid plaques, negatively impacting communication between neurons.

Do Sleep Habits Change for Seniors?

With 10,000 baby boomers becoming 65 every day, the question of sleep becomes highly relevant. The Washington Post says, “Scientists have also discovered the role of telomeres in aging. These are caps on the ends of strands of DNA that protect a cell’s genetic material when it divides. But they get a little shorter with each division, and once they get too short, a cell can no longer function normally. Older people have shorter telomeres, but so do people with high stress and poor sleep habits.”

First of all the myth that seniors need less sleep is – a myth. Dr. Michael W. Smith of WebMD offers the following definitive answer, “As children and adolescents, we need more sleep than we do as young adults. But by our senior years, we need the same seven to nine hours a night we did as teens.” 
On the other hand, the nature and quality of sleep does change as we age.

sleep_puppy_iStock_000015227531MediumHrayr P. Attarian, MD, in a talk before Northwestern Memorial Hospital’s Healthy Transitions Program® said that although we get less sleep as we age, we need the same amount. Older people take slightly longer to fall asleep than younger ones. Also, sleep efficiency falls as we age. The 18 to 30 year olds have 95 percent sleep efficiency; 31 to 40 year olds enjoy 88 percent sleep efficiency; 41 to 50 year olds have 85 percent sleep efficiency and 51 to 70 year olds are down to 80 percent sleep efficiency.

So the bottom line seems to be seniors need as much asleep as ever, but they have a harder time achieving it.

Medications play a part in senior sleep habits, too. As we age we often need more medications to get us through the day and night. Dr. Attarian warned about Tylenol and Advil PM specifically. He said that they worsen prostate conditions in men and that they impair reflexes in both sexes into the next day.

2018 Physical Activity Guidelines Advisory Committee Submits Scientific Report

Eat less; move more; live longer has been the mantra of this blog for years. I am always gratified to see those sentiments echoed elsewhere. The latest version comes from the government of all places and it dwells particularly on the aspect of exercise.

cycling-bicycle-riding-sport-38296.jpeg

The 2018 Physical Activity Guidelines Advisory Committee, a group of nationally recognized experts in physical activity and public health, has submitted its recommendations to the U.S. Department of Health and Human Services (HHS) Secretary and disbanded.

The 2018 Scientific Report reinforces the recommendations included in the 2008 Physical Activity Guidelines that physical activity reduces the risk of a large number of diseases and conditions. In addition to disease prevention benefits, the Scientific Report includes findings that regular physical activity provides a variety of benefits that help people sleep better, feel better, and perform daily tasks more easily. The Committee also found that some benefits happen immediately, on the same day a single bout of physical activity is performed.

Expanding on findings from the Advisory Committee Scientific Report, 2008, the 2018 Committee identified health benefits of physical activity that had not been previously identified including:

Improved bone health and weight status for children ages 3 to 5
Improved cognitive function for children ages 6 to 13
Decreased risk of certain cancers, dementia, and excessive weight gain for adults
Improved quality of life and sleep for adults
Reduced feelings of anxiety and depression in adults
Additional benefits for specific population including older adults, women who are pregnant or postpartum, and individuals with pre-existing medical conditions

Additionally, the Committee found strong or moderate evidence that more time spent in sedentary behavior is related to greater all-cause mortality, cardiovascular disease mortality and incidence, type 2 diabetes incidence, and the incidence of certain cancers.

Get Involved: The Department has published the 2018 Physical Activity Guidelines Advisory Committee Scientific Report online and the public is encouraged to view the Scientific Reportand provide written comments to the federal government at https://health.gov/paguidelines/pcd. The comment period will be open until 11:59 pm E.T. April 2, 2018.

14 Reasons to disconnect on the weekend – Infographic

As an old retired guy, I have to look backwards to remember the intensity of the engagement I felt when I was in the working world. I remember that I considered going to sleep an intrusion on my productive day. I often failed to get a good night’s sleep. Ditto on weekends, you could usually find me in the office on Saturdays. Turns out that neither of those actions was wise.

I am now in my 18th year of retirement. I have been writing this blog for nearly eight years. I think one of the best posts I have done is my Page – How important is a good night’s sleep? I hope you will check it out. Recharging is one of the best and healthiest activities there is for our brain and body. A kind of corollary of not enough sleep is that prolonged sitting hurts us. You can check out my Page – Do you know the dangers of too much sitting? for more details.

Less than 8 hours of sleep psychologically dangerous – Study

I have written extensively about how important a good night’s sleep is to living a healthy life. Now, it seems there are potential psychological vulnerabilities, too. I will give the link at the end of post.

Sleeping less than the recommended eight hours a night is associated with intrusive, repetitive thoughts like those seen in anxiety or depression, according to new research from Binghamton University, State University of New York.

sleep-depression-anxiety-neurosciencenews-public.jpg

Binghamton University Professor of Psychology Meredith Coles and former graduate student Jacob Nota assessed the timing and duration of sleep in individuals with moderate to high levels of repetitive negative thoughts (e.g., worry and rumination). The research participants were exposed to different pictures intended to trigger an emotional response, and researchers tracked their attention through their eye movements. The researchers discovered that regular sleep disruptions are associated with difficulty in shifting one’s attention away from negative information. This may mean that inadequate sleep is part of what makes negative intrusive thoughts stick around and interfere with people’s lives . Continue reading

Why sleep deprivation affects each of us differently

Regular readers know that I am an old man and very highly value a good night’s sleep. That is not the way I felt 20 years ago when I was in the working world. In those days I felt strongly that sleep was an intrusion on my life and activities and resented having to do it. I got a little wiser as the years went by. Please check out my Page – How important is a good night’s sleep? for significantly more details on this very important aspect of living a long healthy life.

1a65fb64-9b1f-4a3d-9074-a2d4f5d918eb

Losing sleep in favor of some good holiday fun a few times each year is nothing to worry about, but chronic sleep deprivation can have adverse health effects. Some of us are affected more than others, however, and new research helps us understand why.

For some of us, it may be harder to perform certain cognitive tasks after a sleepless night.

With 50 to 70 million adults in the United States having a “sleep or wakefulness disorder,” the Centers for Disease Control and Prevention (CDC) consider sleep deprivation a “public health concern.”

Sleep loss is especially alarming given its status as a significant risk factor for traffic accidents and medical mishaps, as well as posing a danger to one’s health.

Insufficient sleep could increase the risk of high blood pressure, diabetes, obesity, and cancer, among others conditions.

Cognitively, sleep deprivation has a wide range of adverse effects. In fact, the CDC report that 23.2 percent of U.S. adults aged 20 and above have trouble concentrating, and another 18.2 percent say that they have trouble remembering things as a result of losing sleep. Continue reading

Eating Fish every week linked to better sleep, higher IQ – Study

Children who eat fish at least once a week sleep better and have IQ scores that are 4 points higher, on average, than those who consume fish less frequently or not at all, according to new findings from the University of Pennsylvania published in Scientific Reports, a Nature journal.
health-benefits-of-eating-fish.jpg

Previous studies showed a relationship between omega-3s, the fatty acids in many types of fish, and improved intelligence, as well as omega-3s and better sleep. But they’ve never all been connected before. This work, conducted by the School of Nursing’s​​​​​​​ Jianghong LiuJennifer Pinto-Martin and Alexandra Hanlon and Penn Integrates Knowledge Professor Adrian Raine, reveals sleep as a possible mediating pathway, the potential missing link between fish and intelligence.

Daylight Saving Time “fall back” doesn’t equal sleep gain – Harvard

Don’t forget to set your clock back tonight before you go to sleep.

Daylight Saving Time officially ends at 2:00 am this Sunday. In theory, “falling back” means an extra hour of sleep this weekend.
Winston Churchill once described Daylight Saving Time like this: “An extra yawn one morning in the springtime, an extra snooze one night in the autumn… We borrow an hour one night in April; we pay it back with golden interest five months later.”

8b273653382c52dac7a0219269c9a889

That’s an overly optimistic view. In reality, many people don’t, or can’t, take advantage of this weekend’s extra hour of sleep. And the resulting shift in the body’s daily sleep-wake cycle can disrupt sleep for several days, according to Anthony Komaroff,M.D., Executive Editor, Harvard Health Letter.

The dark side of blue light – Harvard

Elsewhere in the blog I have written repeatedly about the how valuable it is to get a good night’s sleep. For a full rundown, please check out my Page – How important is a good night’s sleep?

In the meantime, here is an excellent study from Harvard Medical School on our vulnerability to our evening illumination.

aHR0cDovL3d3dy5saXZlc2NpZW5jZS5jb20vaW1hZ2VzL2kvMDAwLzA4NS81NTcvb3JpZ2luYWwvYnJhaW4tbmV1cm9ucy5qcGc=

Exposure to blue light at night, emitted by electronics and energy-efficient lightbulbs, harmful to your health.

Until the advent of artificial lighting, the sun was the major source of lighting, and people spent their evenings in (relative) darkness. Now, in much of the world, evenings are illuminated, and we take our easy access to all those lumens pretty much for granted.

But we may be paying a price for basking in all that light. At night, light throws the body’s biological clock—the circadian rhythm—out of whack. Sleep suffers. Worse, research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity. Continue reading

Give Yourself More Credit for Doing These Things

There are some really nice positive ideas here. What seem like little things often count plenty in the big picture.

Tony

Our Better Health

Let’s do a roll call: who here has been giving themselves a hard time lately? If this is you, it’s time to cut yourself some slack! You may not realize it, but there are countless things you accomplish every day that are absolutely praiseworthy.

No, really! If we don’t give ourselves credit for the small stuff, how can we feel comfortable patting on ourselves when we accomplish something massive?

The next time you start doubting yourself and your capabilities, reflect on this list as a reminder of all that you do that is right as rain. And give yourself some credit – you really deserve it.

1. Catching Some ZZZs

Getting enough sleep every night is not an easy feat! Whether we’re a working parent of triplets or someone who is struggling with managing their anxiety levels, the fact that we get as many ZZZs as we can is a…

5 Habits that work for weight loss – Harvard

I think that deciding to live a healthy life is a far more rewarding goal than ‘losing a few pounds.’ Unfortunately, I think peoples’ eyes glaze over contemplating the general idea of living a health life. Whereas, lopping off a few offending pounds resonates. Statistics show that 60 percent of us are overweight and half of those folks are outright obese. So, we need to know some weight loss techniques. I think Harvard does a good job on this list from the Harvard Heart Letter.

1. Make time to prepare healthy meals

Home-cooked food tends to be far lower in calories, fat, salt, and sugar than restaurant food and most processed food. But it takes time and effort to choose recipes, go to the store, and cook. Take a close look at your weekly schedule to see if you can carve out a few hours to devote to meal planning and shopping, which is more than half the battle, says Dr. Blackburn. It could be on Sunday afternoon or in 15- to 30-minute increments throughout the week. Continue reading

Poor sleep habits related to dementia

I have written about the value of sleep for some years here. It along with walking are two of the most unappreciated aspects of living a healthy life. You can check out my Page – How important is a good night’s sleep? for more details.

I wanted to share the following video with you as it highlights another aspect of the value of a good night’s sleep.

Dr. Breus is a clinical psychologist, and is known for his expertise on sleep and health. He’s a fellow of the American Academy of Sleep Medicine,.

Poor sleep literally causes dementia. It’s one of the causes, and fixing it is one of the ways you can reverse dementia.

Dr. Breus explains exactly how lack of sleep affects your body and brain, and how disturbances in your sleep cycles can “turn on” the progression of dementia, and cause many other serious health problems too.

The good news is that you can avoid mental and physical disorders that poor sleep causes by following easy, at-home recommendations Dr. Breus will give you to cure sleep disorders and sleep peacefully all through the night.

Sleep aids can be risky – Harvard

Sleep is one of the most under-appreciated aspects of living a healthy life. I felt strongly enough about it to devote an entire Page – How important is a good night’s sleep? to it. My assumption was that you are using no extraneous methods of getting yourself down. I don’t recommend taking any kind of drugs to help yourself get to sleep. There are a number of relaxation methods that work wonders and have no ill effects. The Harvard Health Letter warns about taking sleep aids.

100915_fobette-main

Millions of Americans rely on prescription sleep medications, called sedative hypnotics, to fall asleep. While the drugs can help people get a decent night’s rest, they are not designed for long-term use. “Each of the pills has its own risks,” says sleep expert Dr. Lawrence Epstein, an instructor in medicine at Harvard Medical School.

Types of sleep aids

Sedative hypnotics fall into three categories.

Melatonin-receptor agonists such as ramelteon (Rozerem) leave the body quickly. They target melatonin receptors in the brain and are not thought to be habit-forming. Continue reading

Controlling Memory By Triggering Specific Brain Waves During Sleep – IBS

Have you ever tried to recall something just before going to sleep and then wake up with the memory fresh in your mind? While we absorb so much information during the day consciously or unconsciously, it is during shut eye that a lot of facts are dispatched to be filed away or fall into oblivion. A good quality sleep is the best way to feel mentally refreshed and memorize new information, but how is the brain working while we sleep? Could we improve such process to remember more, or maybe even use it to forget unwanted memories?

I would just like to add that my Page – How important is a good night’s sleep? includes further information on how the brain benefits from good sleep habits.

sleep-memory-brain-waves-neurosciencenews.jpg

Scientists at the Center for Cognition and Sociality, within the Institute for Basic Science (IBS), enhanced or reduced mouse memorization skills by modulating specific synchronized brain waves during deep sleep. This is the first study to show that manipulating sleep spindle oscillations at the right timing affects memory. The full description of the mouse experiments, conducted in collaboration with the University of Tüebingen, is published in the journal Neuron.

The research team concentrated on a non-REM deep sleep phase that generally happens throughout the night, in alternation with the REM phase. It is called slow-wave sleep and it seems to be involved with memory formation, rather than dreaming. Continue reading

6 ways your pet can boost your health and well being – Medical News Today

As regular readers know, I am a dog lover . I have posted about my poodle, Gabi, a number of times. She accompanies me on about 5000 miles of bikes rides every year. So, I was very pleased to run across this item by Honor Whiteman on Medical News Today.

On arriving home after a long, stressful day at work, you are greeted at the door by an overexcited four-legged friend. It can’t fail to put a smile on your face. Pet ownership is undoubtedly one of the greatest pleasures in life, providing companionship and giggles galore. But the benefits do not end there; your pet could be doing wonders for your health and well-being.
IMG_2222.jpg

My intrepid little partner, Gabi, in her basket wearing her hat ready to ride.

The United States is a nation of animal lovers; more than 65 percent of households own a pet, with dogs and cats being the most popular choice.

It is no surprise that so many of us have a pet in our lives; not only are animals fantastic company, but they also teach us compassion and offer unconditional love.

As British novelist George Eliot once said, “Animals are such agreeable friends – they ask no questions; they pass no criticisms.”

Adding to pets’ indisputable charm is the wealth of benefits they offer for human health and well-being. We take a closer look at what these are.

1. Lower risk of allergies

Around 50 million people in the U.S. have nasal allergies, and pet dander is one of the most common triggers.With this in mind, it may come as a surprise that pets could actually lower the risk of developing allergies.

One study reported by Medical News Today in 2015 associated exposure to dogs and farm animals in early life with a lower risk of asthma development by school age.

More recent research published in the journal Microbiome found that children who were exposed to household pets prior to birth and up to 3 months after experienced changes in gut bacteria associated with childhood allergies. Continue reading
